I also would prefer to see a G#. However between the two examples, I think the first is slightly more readable.
That said, what are the subsequent A's supposed to be - flat or natural? As written, I would play them as naturals in the first example, but flats in the second example. Were I engraving this, I would put an explicit accidental, whether flat or natural on the fourth A, as well. dB On Thu, Feb 3, 2022, 11:51 AM Kieren MacMillan < kieren_macmil...@sympatico.ca> wrote: > Hi all, > > > Speaking as a keyboard player (and lilypond novice) I would recommend > re-spelling the a flat as a g sharp!
